3 Claims. (Q1. 43-146) This invention relates to an improved container for powder, such as insecticide powder or dust, which can be operated at times as a bellows to dispense the powder therein.

It is therefore an object of this invention to provide a container or bag provided with a perforate diaphragm through which dust, as insecticide and the like, may be ejected from the bag by manually operating the bag as a bellows.

It is a further object of this invention to provide such a dispenser with diaphragm positioned therein for most effective (lust distribution.

It is also an object of this invention to provide a dust dispenser of this class obtainable by making a simple. inexpensive, and positively installed addition to conventional containers now provided for insecticides and the like.

ther and further objects will be apparent when the following detailed description is considered in conjunction with the accompanying drawings in which:

Figure l is a perspective View showing an embodiment of the invention being operated as an inseticide dispenser to dust a plant.

Figure 2 is an enlarged fragmentary section taken along line 2-2 of Figure 1.

Figure 3 is a fragmentary side view showing the perforated diffuser and its mounting on a bag or container.

Figure 4 is an exploded view of the diifuser plate and its mounting means.

referring in detail to the drawings, a flexible and collapsible container ill has side walls 14 connected at their ends by end walls 11 having vertical creases giving them V-shaped cross sections. The container side walls 1d are deflected inwardly at their upper ends to form a \i-shaped top 12 for the container, and the upper extremities of the side walls are folded over each other to close the container.

A diffuser assembly 15 covers an opening 26 provided in one of the side walls 14, and comprises a metal disc 16 having a multiplicity of very small diameter perforations 17 therein, and radially spaced outwardly of such perforations larger diameter holes 18 are provided through which are insertable rivets 19.

The opening 20 is of greater diameter than the perforated center of the disc 16 and of lesser diameter than the outer diameter of the disc. The rivets 19 are passed inwardly through the related bag side wall 14 around the opening 2d,'and a flat ring 21 having holes 22 therein registrable with the rivets 19 is engaged with the inner side of the bag side wall in registry with the disc, as shown in Figure 3, and the rivets are passed through the openings 22 in the ring 21 and peened over so as to secure the disc in place over the opening 20 of bag or container Iltl. It has been determined that for best performance the diffuser plate assembly 15 should be installed near the top of the bag 12 or about two thirds of the way upwardly from the bottom 13' of the bag.

In operation the bag 10 is usually slightly less than full of dust, such as insecticide, and the part of the bag above its contents is compressed like a. bellows so as to force dust through the perforated disc 16. By selection the perforations in the plate are so sized that proper distribution of the dust to be dispensed is obtained for the size of dust particles to be distributed.

Although one modification of the invention has been shown and described hereinabove, it is pointed out that the invention is not so limited but of modifications and variations of both containers and difiuser plate assembiies are deemed to fall Within the spirit of the invention and within the scope thereof as herein claimed.

What is claimed is:

l. A bellows container comprising a flexible and collapsible bag having side walls, creased end walls connecting and extending between the side walls, a bottom wall, and a top comprising upper portions of the side walls deflected inwardly toward each other and having upper extremities folded upon each other to close the bag, one

said side walls having a single opening located between the bottom wall and the top and spaced below said upper portions of the side walls, and a perforated disc assembly secured to said one side wall and covering said opening.

2. A bellows container according to claim 1 wherein a quantity of powder is disposed in said bag below said opening and the part of the bag above the opening is arranged to be compressed to drive air and powder out through the opening and through said assembly.

3. A bellows container according to claim 1 wherein said assembly comprises a perforated disc engaging the outer side of said one side wall, said disc having a peripheral edge portion, a ring engaging the inner side of the said one side wall and registered with the disc, and

fastening means traversing the peripheral edge portion of v the disc, the said one sidewall, and said ring.
